Automatic composition apparatus and method is able to automatically compose a piece of music having a melody that is favorable in a musical sense, namely, a melody that satisfies musical requirements. A storage medium stores a program executed for automatically composing a piece of music having such a melody as described above. After melody pitches are generated under moderate first melody generation conditions, the generated melody pitches are evaluated in terms of more strict second melody generation conditions. With regard to a certain pitch, therefore, it can be determined whether the pitch satisfies musical requirements in view of not only the previous pitch but also the next pitch, thus making it possible to compose a piece of music that as a whole is favorable in a musical sense. Further, since the melody generated in the first stage only includes pitches that meet less strict melody generating conditions, the same melody is less likely to be rejected in the evaluation of the second stage, assuring high efficiency with which melody generation can be accomplished.
